This application claims the benefit of Provisional Patent Application No. 62/185,713, filed Jun. 28, 2015, which application is hereby incorporated by reference along with all references cited therein.
This invention relates to covers for the hand, and more particularly to covers for the hand which incorporate tension activated removal features.
Hand covers of all types have long been used for a great number of purposes. While often necessary for their purpose, they also have drawback associated with them. They often hinder or prohibit the use of the users hands and thus frequently need to be removed and reapplied so that I user can perform tasks with their unencumbered hands and fingers. It is often awkward, time-consuming, or inherently impractical for users to remove their hand covers and reapply them. Users are often faced with removing a hand cover or a portion of a hand cover from one hand while wearing a hand cover on the opposite hand, thus adding and even greater burden to the process. Hand covers of the prior art require both hands for the application and removal process.
The prior art has provided some answers to problems inherent to the use of hand covers. Some gloves, such as the HEAT3 brand, for example, have finger compartments that allow a user to fold them back on themselves and secure them to the rear portion of the glove where they snap into place or are secured in position by a hook and loop style fastener. These fold back gloves and mittens are referred to as “Pop Top” hand covers. While this style is effective it is still time consuming and requires both of a user's hands to operate. Others use a rope or cord to tether themselves to the user's forearm when not in use, but still must be pulled free of the user's hands. The gloves are then left to dangle near the user's hands, making them a further inconvenience, or even perhaps a danger.
U.S. Published Application No. 2013/0039776 shows a white water hand paddle that can break free from a user's hand and remain tethered around their wrist. This may seem useful in that the paddle might not be lost, but whitewater conditions make a hard piece of plastic loosely tethered around the wrist not only inconvenient but dangerous to life and limb.
There also have been many different types of forearm-mounted swimmer's aids that have been used in the past, such as U.S. Pat. No. 2,771,618 that discloses pivoting fins on a forearm sleeve. These types of devices may potentially be used in surfboarding, in that the hand is freed up for handling the surfboard, but rarely are because they have numerous drawbacks and limitations. Simply put, the weight they add to the arm is less than offset by the increase in padding power and efficiency gained. This would perhaps actually increase fatigue associated with moving though the water.
Most surfers do not use paddles or in any way cover their hands. They know that they are going to need to use their free hands to grab and maneuver their boards not merely once but continuously throughout their surfing process. Almost all other water sports benefit from the use of paddles for maximum speed, power, and efficiency. Surfers don't typically use paddles because they constantly require the use of their hands to adjust and position their surfboards and paddles can impede that process. To be of maximum benefit a paddle needs to be positioned in front of the hand exactly where it most impedes the use of a hand.
A surfer must have free hands to grab his board and force it down under an oncoming wave in a maneuver called a “duck dive”. The speed at which a surfer is moving through the water toward a wave and the safety of deeper water is critical to their successful effort to dive under it as opposed to getting washed over the top of it and thrown back toward the shore. Furthermore, a surfer who is able to paddle through the water quickly is more likely to beat large sets of incoming waves entirely by getting out into deep water beyond the depth where they are breaking with greater speed.
A surfer must match the speed that an incoming wave is moving to catch it and thus they paddle excessively as the wave approaches to gain the position and speed required to catch the wave but only have their bare hands or webbed finger gloves to do so. The larger a wave is the faster a surfer must be moving to catch it. Thus a surfer must accurately read the characteristics of an incoming wave, decide whether to pursue it, position themselves and propel themselves through the water at a sufficient speed to catch it. The larger a wave is the larger the amount of time and space is required to do this.
At some point, waves become uncatchable without some sort of aid. Hand paddles can reduce the amount of time and space required for a surfer to respond to a large incoming wave and also increase their acceleration times and peak paddle speeds. This would allow paddle in surfers to catch waves larger than ever before possible.
The added surface area that hand paddles create not only increases acceleration power, but also stopping power, allowing a surfer to brake in the water and back themselves out of dangerous incoming waves that they previously would have had no choice but to allow their forward momentum to carry them straight into. These types of safety concerns are also important. When dealing with large crashing waves and white water conditions, a rigid paddle strapped to your hand or arm could become a dangerous weapon capable of causing severe damage to a surfer and/or others if caught and tossed about by the force of the surrounding water. For safety reasons, a paddle's design should include padding, be as compact as possible when not in use, be able to open and close easily, and remain closed under the turbulence and force of hostile and unpredictable water forces and conditions.
As another concern associated with surfing, the constant repetitive motion of the swimming stroke makes serious joint problems more likely. By transferring more of the work of paddling from the joints to the muscles, reduction of injuries can be achieved.
The prior art to date has not provided a safe, timely, and functional answer to the many problems posed by the application, removal, and stowing hand covers as addressed above.
One aspect of the invention involves an arm-mounted hand paddle with a sleeve configured for securement about the forearm of a user. The sleeve has a pivot post to which a multi-levered scissor assembly is attached thereto at its fulcrum. A tensioning member connected to at least two of the levers tension them toward one another. A ribbed paddle blade is connected to the scissor assembly. A harness connected to the blade is configured to engage at least one finger of the user.
Another aspect of the invention involves an arm-mounted hand paddle with a sleeve configured for securement about the forearm of a user. A guide track on said sleeve, oriented to align with the length of the forearm, has a track follower therein. A tensioning member connected to the track and track follower tensions the follower toward the proximal of the track. A multi-levered scissor assembly has its fulcrum attached to the track follower. A rein is attached to the track follower and is positioned to traverse the user's hand. A harness configured to engage at least one finger of the user is connected to the rein. A collapsible paddle blade is connected to the harness and the scissor assembly.
A further aspect of the invention involves an arm-mounted hand paddle having a sleeve configured for securement about the forearm of a user. A collapsible paddle blade connected to the sleeved is tensioned to collapse the blade into a closed position. A harness connected to the blade is configured to engage at least one finger of the user so that extension of the finger urges the blade toward an opened position.
The objects and advantages of the present invention will be more apparent upon reading the following detailed description in conjunction with the accompanying drawings.
For the purpose of promoting an understanding of the principles of the invention, reference will now be made to the embodiments illustrated in the drawings and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended, such alterations and further modifications in the illustrated device and such further application of the principles of the invention illustrated therein being contemplated as would normally occur to one skilled in the art to which the invention relates.
Major features of the paddle blade 12 include finger pocket 18, used as a harness to operate the hand paddle 10; an oblong slot 20 (
Major features of tensioning mechanism 14 include (
Tensioning mechanism 14 parts may be made of various suitable materials such as stainless steel, polycarbonate, acrylic and/or ABS plastics, to name a few. Tensioning member 38 may take the form of an elastic band or bungee-type cord (shock cord) and may be made out of elastic material, such as butyl rubber, for example. The tensioning bands may be made to be changeable, allowing a selection of tensioning options, and for ease of replacement when worn.
Major features of the sleeve 16 include band 48; cinching ring 50; band flap 52 and fastener 54. Band 48 is typically made of foamed neoprene, although other suitably similar materials may be used. Cinching ring 50 may be made of stainless steel or common plastic substitutes therefore, such as polycarbonate, for example. Fastener 54 is shown in the form of a hook and loop fastener closure, popularly known in connection with the Velcro trademark, although other types of fasteners may be used, such as snaps or buttons, for example.
The sleeve and the entire paddle should be made as light and durable as possible. A non slip coating (not shown) may be added to one or both sides of sleeve 16 to help secure it in position. Optionally, sleeve 16 could clip to, or secure itself under, a wetsuit sleeve to reduce or even eliminate the need for a separate band and fastening system to minimize weight.
When used, a person places a hand through sleeve 16 such that the cuff of sleeve 16 is positioned adjacent the wrist area (

Referring to
In operation, tensioner plate 266 is forced forward by its connection to finger pocket 18 and blade 12, which connects to the ends of the tension levers by a means similar to that described in the first preferred embodiment. In this tensioning mechanism 21, the tension levers 240 connect to plate 266 in the back of the apparatus and is pulled forward to open the unit. The levers are guided out and to the sides.
On the front and back ends of cover 222 are small groves cut into each side of the track. They are V shaped and to fit the correspondingly V shaped extensions on spring loaded button 262. This is to provide a resistance catch to help keep the paddle open when opened and closed when closed unless the excerpts a set amount of force pushing back or pulling forward the finger pocket. A small catch may be added at the base of the finger pocket so that the fingers can catch it and push the paddle back with sufficient force to push the V on button 262 out of the V shaped slot on cover 222. This is to help the paddle stay open if desired to prevent fatigue caused by the user's hand always having to keep pressure on the glove to prevent the tension from closing it. Many catch systems are available and could be used here. In addition to this the tension band if connected to the two extension levers, would counter act itself when the levers are at a 180 degree angle from each other making it easy to keep the glove open. Once the tension levers are pushed to about a 170 degree angle from each other the tension band connecting them would act with greater force to pull them back and close the glove.
While these are illustrated preferred embodiments of the paddle it should be noted that the tension system is an added benefit which automatically closes the paddle. The paddle could operate without it and be manually pushed close by the user's hand. The apparatus could also be designed to use only a front sliding pull open cover, without the expanding sides. Or expanding sides without the front portion covering the hand provided there was a harness or other connection means to the fingers to pry open the paddle. They could both work independently of each other if desired. If the paddle blade itself is made of a sufficiently stretchy material it could provide enough tension to pull itself closed without any additional springs or tension bands.
A cover made of material with elastic properties such as latex could be used to add both tension and padding to the unit. The springs or tension bands used in the system could then be supplemented or eliminated.
If the blades, or the perimeters of the paddle which connect to the expansion arms are made of non stretching or minimally stretchable material, then Prying forward the finger pocket secured to the blades or the inflexible perimeter would in turn force the expansion arms to open that's opening the glove. For example, if an inflexible cable could be run through a pocket from the end of one tension lever, around the finger pocket, and to where it connects to the tension lever on the other side of the paddle. When the finger pocket was pushed forward the tension levers would be pushed forward with them to open the paddle. If secondary slave tension levers were used the above method would open them too via their connections to the primary tension levers as previously described. The finger pocket in all embodiments are designed and positioned so that the user's fingers can easily and readily slip into or out of it to operate the hand cover.
Also, while the preferred embodiments shown have all used scissoring or pivoting tension levers to expand the paddle, firm side panels could be used with a raised lip, slot and groove system (slots on either the forearm mounted base and raised lips on the sliding side panels. The raised lips would be angled forward and outward from the rear center of the unit so that when the finger panel is pried forward, it forces the connecting side panels forward and they are guided out to the sides of the paddle by the correspondingly angled slots and grooved lips in much the same way that the pivoting tension arms are forced out and to the sides when the finger pocket is pried forward. The raised lips may have a bracket attached to the top of them to prevent the sliding side panels from slipping of the top of them. (Not shown)
Once opened the glove can be pushed closed by folding tops 202 and 206 over until they contact the bottom side of the glove where they contact the bottom side of the glove to close as seen in
Many such options are available to lock the top and bottom of the glove including a magnet lock which could be pushed out by the thumb and fingers inside the glove to release the top parts of the glove and open the system as well as numerous other button style lock releases. If desired the lock could be placed only on the thumb and trigger finger of a separately fingered glove. Also in a mitten-style hand cover room could be left in the thumb section so that the thumb could be slid out into the main finger area of the glove to activate a release mechanism which could open the very front of the main finger area of the mitten and then pull the top and bottom portions of the glove back onto the forearm and out of the way via a tension mechanism and track leading up onto the forearm in much the same way as paddle version in
While the invention has been illustrated and described in detail in the drawings and foregoing description, the same is to be considered as illustrative and not restrictive in character, it being understood that only preferred embodiments have been shown and described and that all changes and modifications that come within the spirit of the invention are desired to be protected.
